Lyrics of Welcome to happiness

Welcome to happiness
No smoking allowed
Here it's so easy to burn yourself
And equally hard to survive
Taste the sweat on your upper lip
Welcome to hunger and thirst
Welcome to happiness
It may appear shocking at first
Welcome to longing
To wanting to taste and to touch
Mind the gap, here's depending
Here is wanting too much
Be ready to go
You'll never know when
You'll never know why
Take off any time
